NEC IPASOLINK alarms and status

In this post I am detailing the various alarms in ZTE NEC Minilink used in telecom systems. I have this by searching a lot so I think this would help you a lot in diagnosing the minilink problem.

Minilink NEC alarms and their description

2. TX power - TX power is lower than 3 dB

3. RX level - the reception level is lower than -72 dBm

4. ODU/CPU cable open- this alarm occurs due to the fault in the IF Cable or in the IF connector. 

5. Module alarm - this alarm occurs when the IDU becomes faulty.

6. High BER - this alarm is generated due to the degradation of the radio signals. This alarm generally occurs in the bad weather conditions due to rain, clouds. This alarm can also be there due to the misalignment of the hop antenna.
